@Saltsi 's explanation worked perfectly! I came back to my computer, and it had a dark screen after rebooting itself. I hooked it up to an external monitor using duplicate, did the EDID override, disabled the internal monitor, reinstalled (cleanly) the nvidia drivers and rebooted. Lo and behold the screen came on and has stayed on even after rebooting multiple times and removing the external monitor. Running at full 1440p and 120hz, no issues.
